The resonant structure of the reaction (B) over bar (0) --> J/psi pi(+)pi(-) is studied using data from 3 fb(-1) of integrated luminosity collected by the LHCb experiment, one third at 7 TeV center-of-mass energy and the remainder at 8 TeV. The invariant mass of the pi(+)pi(-) pair and three decay angular distributions are used to determine the fractions of the resonant and nonresonant components. Six interfering pi(+)pi(-) states, rho(770), f(0)(500), f(2)(1270), rho(1450), omega(782) and rho(1700), are required to give a good description of invariant mass spectra and decay angular distributions. The positive and negative charge parity fractions of each of the resonant final states are determined. The f(0)(980) meson is not seen and the upper limit on its presence, compared with the observed f(0)(500) rate, is inconsistent with a model where these scalar mesons are formed from two quarks and two antiquarks (tetraquarks) at the eight standard deviation level. In the q (q) over bar model, the absolute value of the mixing angle between the f(0)(980) and the f(0)(500) scalar mesons is limited to be less than 17 degrees at 90% confidence level

Structure of the decay _ B0s. J=.p_p- is studied using data corresponding to 3 fb- 1 of integrated luminosity from pp collisions produced by the LHC and collected by the LHCb detector. Five interfering p_p- states are required to describe the decay: F-0(980), F-0(1500), F-0(1790), F-2 (1270) and F-2(1525) An alternative model including these states and a nonresonant J=.p_p- component also provides a good description of the data. Based on the different transversity components measured for the spin- 2 intermediate states, the final state is found to be compatible with being entirely CP odd. The CP- even part is found to be < 2.3% at a 95% confidence level. The f 0d500_ state is not observed, allowing a limit to be set on the absolute value of the mixing angle with the f 0d980_ of < 7.7 at a 90% confidence level, consistent with a tetraquark interpretation of the f(0)(980) substructure

NonleptonicBsto charmonium decays: Analysis in pursuit of determining the weak phaseβs

We analyze nonleptonic B s decays to a charmonium state and a light meson, induced by the b ! c " cs transition, which are useful to access the B s -" B s mixing phase s . We use generalized factorization and SUð3Þ F symmetry to relate such modes to correspondent B decay channels. We discuss the feasibility of the measurements in the various channels, stressing the importance of comparing different determinations of s in view of the hints of new physics effects recently emerged in the B s sector. Finally, adopting a general parametrization of new physics contributions to the decay amplitudes, we discuss how to experimentally constrain new physics parameters.
